Abstract

In this paper, a method for scale-reconstructible Structure from Motion to improve the robustness of three-dimensional (3D) reconstruction with a thin plate is proposed. Scale-reconstructible Structure from Motion is a 3D measurement method with an absolute scale using a single camera and a refractive plate. However, previous studies need a large thick refractive plate to achieve scale-reconstructible Structure from Motion. To solve this problem, a weighting factor according to the amount of refraction for optimization of 3D reconstruction was designed. It was confirmed that optimization using the weighting factor is effective for the robust 3D reconstruction method by simulation experiment.
